• If there is too little inventory then this takes up space, may get in the way of production and costs money

• If there is too much inventory then this takes up space, may get in the way of production and costs money

• If there is just enough inventory then this takes up space, may get in the way of production and costs money

Motion in lean production refers to the health and safety risk for employees, specifically the movement of machines that may not be necessary.

What is over-processing in the context of lean production?

• If complex machinery is being used to perform complex tasks then this is efficient

• If simple machinery is being used to perform complex tasks then this is wasteful

• If simple machinery is being used to perform simple tasks then this is efficient

• If complex machinery is being used to perform simple tasks then this is wasteful

Answer explanation

• Any faults require the goods being fixed and time can be saved inspecting the products

• Any faults require the goods being fixed and time can be wasted inspecting the products

• Any faults require the goods being fixed and time can be saved not inspecting the products
